The chromosomal complements of five species of mammals, Mus musculus (Linn.), Rattus rattus rattus (Linn.), Bandicota bengalensis (Gray and Hardw.), Funambulus pennanti (Wr.) and Lepus ruficaudatus (Geoff.) were elaborated. The karyotypes of all the species were compared. The diploid number (2n) in Mus is 40, Rattus 42, Bandicota 42, Funambulus 54 and Lepus 48. An extra large X-chromosome was observed in one population of male Rattus rattus rattus (Linn.), which might have been formed as a result of duplication of the terminal segments of both the arms of the chromosomes.
对五种哺乳动物，即小家鼠（林奈）、黑家鼠（林奈）、板齿鼠（格雷和哈德威克）、笔尾树鼩（沃克）和赤尾松鼠（ Geoff.）的染色体组进行了详细研究。比较了所有物种的核型。小家鼠的二倍体数（2n）为40，黑家鼠为42，板齿鼠为42，笔尾树鼩为54，赤尾松鼠为48。在一群雄性黑家鼠（林奈）中观察到一条超大的X染色体，它可能是由染色体双臂末端片段的重复形成的。
